Python进阶利用第三方库aiohttp进行异步编程

    UA = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36'
    
    
    async def fetch_title(url):
    # session用完了是需要关上的，所以要利用上下文语法with
    async with aiohttp.ClientSession() as session:
        async with session.get(url, headers={'User-Agent': UA}, ssl=False) as resp:
            # ssl=False是为了不进行网站验证
            page_code = await resp.text()
            # 如果是拿二进制数据就是resp.read()
            match = TITLE_PATTERN.search(page_code)
            if match:
                p
